#include <B2BITS_IceImpactApplication.h>
IceImpact::Application runtime parameters. These parameters can be global (use same values for all servics), or specified at service level

| std::string IceImpact::RuntimeParameters::licenseFile |
License file Default value: "./b2b_ice_impact.license"
Number of seconds before ServiceListener::Notification::LinkDown notification is generated. If this property is set to 0 - LinkXXX notifications are not generated.
Default value = 0
| std::string IceImpact::RuntimeParameters::logConfigFile |
Logging sub-system configuration file Default value: "./log.properties"
| std::string IceImpact::RuntimeParameters::logDirectory |
Path of the directory where the log files will be created. Default value: "." - current directory
| bool IceImpact::RuntimeParameters::logIncomingBinaryMessages |
Log incoming messages to binary files. All incoming UDP and TCP messages will logged to the files in binary format.
Default value: false
- Note
- Setting this value to true, will impact up the performance.
| bool IceImpact::RuntimeParameters::logIncomingMessages |
Log incoming messages as text. All incoming UDP messages will logged as text to the log file.
Default value: false
- Note
- Setting this value to true, will have an impact on performance.
| TCPParams IceImpact::RuntimeParameters::tcpParams |
| UDPParams IceImpact::RuntimeParameters::udpParams |
| bool IceImpact::RuntimeParameters::useNaturalRefresh |
This option disables Snapshot recovery and leaves TCP replay enabled. Instead of initiating recovery, service clears books of all instruments. onInstrumentReset event is generated for each affected instrument with ResetReason::rrNaturalRefresh for user reference. The instrument price books are getting gradually populated by incremental book updates coming over UDP. Late join does not initiate Snapshot recovery. Default value: false
- Note
- Please note that in case of 'natural refresh' state of book is not restored immediately, and there is no way to find out when the book contains consistent data. This mode is for debugging purposes only, to be used in environments with high degree of packet loss Set to
true at your own risk.
-
This setting is not recommended for production use. Default value:
false
| bool IceImpact::RuntimeParameters::useNaturalRefreshOnGap_FOD |
Works similarly to useNaturalRefresh, the difference is that Snapshot recovery is enabled, TCP replay is disabled. This setting affects Full Depth UDP multicast groups only. Instrument book reset and natural refresh is triggered only when UDP data gap is detected, late join and major packet loss triggers Snapshot recovery. Snapshot recovery may be abandoned if gap on the live channel is detected and natural refresh is triggered. When the setting is enabled, the user should be prepared for a loss of some add/delete order messages. Default value: false
| bool IceImpact::RuntimeParameters::useNaturalRefreshOnGap_TOB |
Works similarly to useNaturalRefresh, the difference is that Snapshot recovery is enabled, TCP replay is disabled. This setting affects Options TOB UDP multicast groups only which carry top of the book data. Instrument book reset and natural refresh is triggered when UDP data gap is detected, late join and major packet loss triggers Snapshot recovery. Snapshot recovery may be abandoned if a gap on the live channel is detected and natural refresh is getting triggered. This is setting is relatively less risky because incremental changes are transactional by nature since there's just one price level sent on Options TOB channels. There's no risk to get wrong prices, but some of other messages like market event or trade may be lost since TCP replay is not used.
- Note
- This setting is not recommended for production use. Default value:
false
| bool IceImpact::RuntimeParameters::useNaturalRefreshOnGap_TOP5 |
Works similarly to useNaturalRefresh, the difference is that Snapshot recovery is enabled, TCP replay is disabled. This setting affects Futures TOP5 UDP multicast groups only (5 price levels). Instrument book reset and natural refresh is triggered only when UDP data gap is detected, late join and major packet loss triggers Snapshot recovery. Snapshot recovery may be abandoned if a gap on the live channel is detected and natural refresh is getting triggered. When the setting is enabled, there's the risk to have incomplete book at certain moments when some levels are available and some are not yet. BBO (top level updates) may sometimes arrive with null values (signifying no TOB level exists) because the last available level may be removed from incomplete book
- Note
- This setting is not recommended for production use. Default value:
false
| bool IceImpact::RuntimeParameters::useTCP |
Enable/Disable the use of ICE TCP server. When TCP is disabled, TCP replay of dropped packets will not happen, and snapshot recovery (or natural refresh) will be triggered immediately. Also, loading of instruments from ICE via TCP will not be available. Note that it is possible to load instrument definitions from external file.
- Note
- This setting is not recommended for production use. Default value: true
| bool IceImpact::RuntimeParameters::useTCPReplay |
Enable/Disable the use of ICE TCP server for replays. When TCP Replay is disabled, retriavle of dropped packets will not happen, and snapshot recovery (or natural refresh) will be triggered immediately.
- Note
- This setting is not recommended for production use. Default value: true
